<![CDATA[Beach volleyball is a popular game in which players must possess different physical abilities to achieve the desired goal, including explosive power, speed, motor speed, reaction speed, agility, flexibility, and endurance, which play a significant role in developing skill capabilities. This study aims to prepare complex (physical-skill) exercises using the Verti Max device to establish the motor speed of the legs and the accuracy of performing the skill of defending the court for beach volleyball players, as well as to know the effect of complex exercises using the Verti Max device on developing the motor speed of the legs and the accuracy of performing the skill of defending the court for beach volleyball players. To solve his problem, the researcher employed the experimental method by designing two equivalent groups: an experimental and a control group, with pre- and post-tests. The researcher deliberately selected the research sample, which is the players of the Akso Club in beach volleyball for the season (2024/2025), whose number is (4) players, constituting (50%) of the total community. The results showed statistical significance for the post-tests for both groups, but more in favor of the experimental group and for all variables. The researcher reached several conclusions, the most important of which is that the compound exercises using the Verti Max device have a positive effect on developing the motor speed of the legs and the accuracy of performing the skill of defending the court for beach volleyball players, which contributes to guiding coaches, teachers and players based on such exercises for the purpose of developing their physical and skill level.]]>
